Automatically determining dead band DBND by running X.TUNE:
When X.TUNE is running, the dead band can be automatically determined depending on the friction
behavior of the actuating drive.
Before running X.TUNE, the X.CONTROL auxiliary function must be activated by incorporating it into the
main menu (MAIN).
If X.CONTROL is not activated, a fixed dead band of 1 % is used.
The changed data is saved in the memory (EEPROM) only when there is a switch to the process level,
by leaving the main menu (MAIN) using the left selection key
EXIT
. During the save process, the save
symbol is indicated
on the display.
